Back to Article Information || Previous Figure ||Next Figure >>

Nutrient contributions to the Gulf, by State

(Estimated contributions are listed, by state, in descending order, in Tables 4 and 5 in the ES&T supplemental material, pages 22-25)

Nine states in the Mississippi River Basin with the largest nutrient deliveries to the Northern Gulf of Mexico contribute more than 75 percent of the nitrogen and phosphorus to the Gulf, but make up only one-third of the 31-state Mississippi River drainage area. These states include Illinois, Iowa, Indiana, Missouri, Arkansas, Kentucky, Tennessee, Ohio and Mississippi.
